A bundle of singlewalled nanotubes processed into a thin sheet is shown in this scanning electron microscope image. Singlewalled nanotubes are extremely important in the continuing miniaturization of electronic devices. These tubes have an average diameter of 1-2 nm. Their electrical properties have led to their investigation as super capacitors for storing electrical charges.
• SIZE: The thickness of the sheet is about 50 µm.
• IMAGING TOOL: Scanning electron microscope
